Description of the Invention: [Technical Field] The present invention relates to a power line internet access device, and more particularly to a power line internet device having both a DC power output and a network signal connection function. [Prior Art] ❹ ❹ Due to the effect of network popularization, the monitoring system has the function of remote monitoring system due to the establishment of the network. However, the network and power lines must be built on the monitoring side, and each monitoring The device must have the function of accessing the Internet. Therefore, although the popularity of the Internet can be used to achieve the effect of remote monitoring, the setting of the monitoring terminal increases the trouble of the network route and the power line arrangement. There is a power line Internet access device on the market, which is mainly connected to the external network device. It is replaced by a power line. In short, the power line Internet device is connected to the power line and the network line. The power material is connected to the (4) source to obtain the working power, and the network cable is for the electronic device with the network card; the electronic device wants to connect: when the Internet is connected, the network signal can be transmitted through the network route. To the power line Internet:: After being processed by the power line Internet device, it is coupled to the power line. With the layout of the line network, the network is also connected to the remote line and connected to the second line. = Similarly, the electronic device is also The power line network device can take θ, + from the power line network to pick up the network signal sent by the remote network device; 疋, the power line network device is compared with the cab machine, etc., but the other is less than the ADSUXDSL data machine, so Remote monitoring - Γ line or coaxial line. For the control system, the network camera can directly cooperate with 4 200926641 Ο
